Why is it impossible to add JFrame to a JFrame? 为什么不可能将JFrame添加到JFrame？ It's just adding a Component to a Container. 它只是向容器添加一个组件。 How Java prohibits me from doing so? Java如何禁止我这样做？ Yes, I know doing it doesn't make sense, but the point of my question is to understand Swing mechanism - how it works under the hood. 是的，我知道这样做是没有意义的，但是我的问题的重点是了解Swing机制-它是如何在后台运行的。
